e-NABLE Prosthetic Emulator for evaluating Terminal Devices

Postby Skip Meetze » Mon Apr 04, 2016 3:15 pm

The e-NABLE Prosthetic Emulator straps onto the arm of an able-bodied person to allow evaluation of upper limb prosthetic Terminal Devices (TDs). It can be an aid to clinicians when they train the amputee in the use of a prosthesis. It also is useful to designers as a testing device for experiencing experimental Terminal Device designs in use.

The Emulator is easy to fabricate with
  • printed parts and
  • a 1 1/4 inch plastic pipe.
  • It attaches to the Terminal Device with the standard 1/2-20 screw thread (or M12 fine thread where metric is used).
  • A standard Bowden cable can be fabricated from a String trimmer filament (or nylon 1.75mm printing filament) and a printed bead.
  • The cable is attached to the Emulator (for elbow-powered operation) or to a shoulder harness in the conventional manner.

This is a new design that is evolving for use by e-NABLE volunteers to develop new experimental designs for assistive devices. The design and instructions will be updated from time to time based on testing and feedback.
